The A6M Zero is carrier-based fighter aircraft manufactured by Mitsubishi and was considered the best carrier-based fighter aircraft since the time it was produced.

During 1940-1941, the pre-series A6M2 Zero became known, when the fighter was confirmed to have destroyed 266 aircraft in China. During Pearl Harbor, there were 420 Zeros in active service in the Pacific. In 1941, the Zero fighters were superior in many performance aspects to all Allied fighters in the Pacific and it quickly gained reputation. However, the Zero failed to achieve air superiority when suitable tactics and new aircraft were developed by the Allies. During World War II, the Zero destroyed at least 1,550 American aircraft.

The A6M5 is an updated model of the A6M3 Model 22, with nonfolding wing tips and thinner skinning for faster diving speeds, plus an improved exhaust system which provides an increment of thrust. There are three subvariants of the A6M5, the A6M5a Model 52a, A6M5b Model 52b and A6M5c Model 52c. The A6M5 could travel at 540 km/h and can reach a height of 8,000 meters in nine minutes and 57 seconds.

There were several Zero fighters which survived the war and were currently on display in Japan, China, United States and the UK, as well as the Auckland War Memorial Museum in New Zealand.
